GIRDER-J O I NT FOR RAILROAD-RAILS.

SPECIFICATION forming part of Letters Patent No. 496,916, dated May 9,1893.

Application filed J'uneZ'], 1892.

To all whom it may concern.-

Be it known that I, ll/IAXIMILIAN M. SUPPEs, a resident of Johnstown,Pennsylvania, have invented a new and useful Girder-Joint forRailroad-Rails, of which the following is a specification.

This invention relates to girder joints for railroad rails, and has forits object to provide a girder joint of great strength, which willfirmly seat the abutting ends of rails and bind the latter in place.

The invention consists of a girder jointfor railroad rails and indetails thereof as hereinafter described and claimed.

In the accompanying drawings: Figure l is a view in cross section of agirder joint constructed in accordance with this invention and Fig. 2 isa perspective view thereof showing the abutting ends of two railssecured in place. Figs. 3 and 4 are views of modifications similar tothose in Figs. 1 and 2 but showing the girder member provided with baseflanges.

1 indicates the abutting ends of rails rolled with lower dependingflanges 2, preferably of curved shape, forming a channel or pocket inthe bottom of the rail, and 3 is a girder bar, formed with a bead or rib4, projecting from and extending lengthwise on its top. The bead or rib4 is shown to be of such size asto partly fit into the channel formed bythe flanges 2 of the rails 1, leaving a space be tween the bead 4 andthe upper part of the channel formed by flanges 2. This arrangement ofbead and channel is incidental to the rolling of the flanges 2 of therails shown, and they both may be of such size and relation to eachother that the bead will entirely fill the channel.

5 indicates side members, which serve as a chair, and are formed withthe vertical portions 6, to lie against the webs of the rails 1, thepreferably curved shoulders 7, conforming to the sides of the curveflanges 2 of the rails 1; lateral recessed portions or offsets 8, whichinclose the flanges of a T bar 3; lower vertical portions 9, and flanges10 to rest upon and be secured to ties. The side members may be variedin form from that shown and described, they being provided with aclamping upper portion, a lateral oifset, and a shoulder between theupper portion and the flerial No. 438,200. (No model.)

offset. Any other form of bar with a longitudinal rib on its top may beemployed in place of the girder bar 3. The girder joint is formed byplacing a girder bar 3 between two side members 5,with the flanges ofthe girder bar 3 resting on the offsets 8 and the curved flanges 2 ofthe abutting ends of two rails 1, resting on the bead or rib 4 of thegirder bar 3. The parts are fastened together by bolts 11 extendingthrough the vertical portions 9 of members 5, and the web of the girderbar 3, and bolts 12, extending through the vertical portions 6 ofmembers 5 and the webs of rails 1. The bolts 11 and 12, are tightenedby'means of nuts 13. In tightening the parts together, the drawingtoward each other of the vertical portions 9 of members 5, by screwingup the nuts 13 on bolts 11, brings an upward pressure of the parts ofmembers 5 on which the flanges of girder bar 3 rest against said flangesand a pressure of the'shoulders 7 against the flanges 2, thereby on theone hand forcing the bead or rib 4 up into the channel or pocket formedby flanges 2, and on the other hand drawing the shoulders 7 against theflanges 2 and thereby forcing the latter against the bead 4. By thismeans the flanges 2 are seated in place and tightly clamped between thebead 4 and shoulders 7; and when the vertical movement of the rails frompounding of the joint occurs, the tendency of the parts will be to causethe flanges 2 to be clamped between the bead 4 and shoulders 7. When theside members are thus secured, their vertical portions 6 will be clampedagainst the webs of rails 1, and the flanges 2 of rails 1 will liesnugly between the sides of bead or rib 4, and the curved shoulders 7 ofside members 5. By means of this construction and arrangement of parts,the abutting ends of rails 1 will have a firm bearing in the joint, asany tendency to vertical movement of the ends of the rails frompounding, will be prevented by the firm bearing of the flanges 2,clamped between the bead 4 of T bar 3, and the curved shoulders 7 ofside members 5. If desired the girder member 14 may be employed,provided with base flanges l as in Figs. 3 and 4, to secure the joint toties, in which case the flanges upon the side members may be dispensedwith.

I do not intend to limit myself to the form ties, of a girder barfprovided with a bead or rib extending from top of said bar, the pocketsof said rails being adapted to receive said bead; and side membersoffset to form a seat for the head of the girder bar and secured to saidabutting rails and girder member.

2. The combination with two abutting rails, formed with pockets at theirlower extremities, of a girder bar provided with a bead or rib extendingfrom the top of said girder bar, the pockets of said rails being adaptedto receive said bead; and side members offset to form a seat for thegirder bar and secured to the Web of thegirder bar and the webs of theabutting rails.

3. The combination with two abutting rails, formed with pockets at theirlower extremities, of a girder bar provided with a bead or rib extendingfrom the top of said girder bar, the pockets of said rails being adaptedto receive said bead; and side members offset to form a seat for thebead of the girder members and conforming to the outer sides of thepockets of said rails, the side members being secured to the abuttingrails and the girder bar.

4. In a girder joint, .two abutting rails, flanges at their lowerextremities forming a pocket in combination with a girder bar providedwith a bead or rib extending from its top and side members inclosing thegirderbar and the webs of the rails the head of the girder bar beingwedged between the rail flanges forming the pocket, and the said railflanges being clamped between the bead and the side members.

5. In a girder joint, two abutting rails, having flanges at their lowerextremities forming a pocket in combination with a girder bar providedwith a bead or rib extending from its top projecting into said pocket,and side members secured to the rails and girder bar, the head of thegirder bar being wedged between the pocket flanges of the rails and saidflanges being clamped between the bead and the side members.
